| 目的 探讨99Tcm-MIBI脑肿瘤阳性显像在评价脑胶质瘤恶性程度的价值。方法 对恶性脑胶质瘤患者行脑SPECT显像,用ROI技术勾划肿瘤、健侧本底和垂体的平均计数及最高计数,分别比较肿瘤/健侧本底最高及平均计数比(T/NT1及T/NT2)、肿瘤/健侧本底计数比肿瘤/垂体最高及平均计数比(T/NT3及T/NT4)在评价肿瘤恶性程度之间的差异。结果 在判断肿瘤恶性程度,应用T/NT3及T/NT4时,高度恶性组和低度恶性组之间的差 |

| Objective To investigate the clinical values of 99Tcm-MIBI imaging in evaluating malignant degrees of brain glioma. Methods The patients who were diagnosed as brain glioma by pathology underwent 99Tcm-MIBI SPECT imagings before operating. By using regions of interest (ROI) technique, the differences among the tumor highest count/normal tissue highest count (T/NT1), tumor mean count/normal tissue mean count (T/NT2), tumor highest count/pituitary highest count (T/NT3) and tumor mean count/pituitary mean count (T/NT4) were compared to evaluate the malignant degrees of brain gliomas. Results In evaluating the malignant degrees, when using T/NT3 and T/NT4, there were significant difference between high degree malignant group and low degree malignant group, and using T/NT3 and T/NT4 was more valuable than using T/NT1 and T/NT2. Conclusion 99Tcm-MIBI imaging has high value in identifying the malignant degree of brain glioma. |
